RAILWAY-SPIKE PULLER OR EXTRACTOR.

SPECIFICATION forming part of Letters Patent No. 463,145, dated November17, 1891.

Application filed May 18, 1891.

To all whom it may concern.-

Be it known that I, PHILIP FOWLER, a citizen of the United States ofAmerica, residing at WVayne, in the county of WVayne and State ofNebraska, have invented certain new and useful Improvements inRailway-Spike Pullers or Extractors, of which the following is aspecification, reference being had therein to the accompanying drawings.

This invention relates to a spike puller or extractor, having for itsobject the production of a device of this character which will occupybut a minimum amount of space and which can be made to operate upon thespikes in narrow or close quarters, and which will also pull or extracta spike without bending or twisting the same, and which will readilygrasp the head of the spike.

The invention further comprises a lever fulcrumcd between two parallelposts and having two corresponding depending links, two dogs or jawshaving upper slotted ends loosely secured to said links, and a mainoperating-lever, also fulcrumed between said posts, connected to saidformer lever, substantially as hereinafter fully set forth, andparticularly pointed out in the claims.

In the accompanying drawings, Figure l is a view inside elevation. Fig.2 is a front end view. Fig. 3 is a detail View of the dogs or jaws. Fig.4 is a vertical sectional view thereof, showing the fulcrum pin or bolt.

Referring to the drawings, A designates a base or platfor1n,which ispreferably oblong, and a two parallel vertical bars or posts, rigidlysecured to and projecting from said base or platform at one end thereof.

B is the main operating-lever, which at its inner end is pivotallysecured between bars or posts a at the upper ends thereof by a nuttedbolt 1). These bars or posts a are braced in position by two inclinedrods or bars I), the upper forward ends of which are secured by the bolt1), passed through coincident holes or apertures, and their lower outerends are rigidly secured to base or platform A.

O is a second lever fulcruined by a bolt cl, passed through either oneof two sets ofv coincident holes or apertures d in bars or posts a. Atits rear end lever O is connected to le= ver B by two parallelstrap-irons or links d while to the outer forward end of lever CareSerial No. 393,096. (No model.)

pivotally connected by a bolt 6 the upper ends of two correspondinglinks E, having lower slotted ends e.

F F designate two dogs or jaws, which are pivotally connected togetherbya nutted bolt f, passed through coincident holes or apertures thereofand held by a nut f on the threaded reduced end f the head of said boltbeing countersunk in the outer dog or jaw. The lower ends of these dogsor jaws are curved and flattened, so as to grasp the head of a spike. Inthe upper ends of these dogs or jaws are oblong slots f through whichnutted bolts f are passed for securing said dogs or jaws to the lowerslotted ends e of links E, said holtsf being passed through coincidentholes or apertures of said links. By thus providing the dogs or jawswith upper slotted ends the same will readily assume the desiredposition with relation to the spike and can be easily made to grasp thehead thereof.

In practice the lever O is generally fulcrumed near the upper ends ofthe bars or posts, its bolt 01 being passed through the upper set ofholes or apertures cl. Where the space at which the puller or extractoris to operate is narrow or limited the bolt (Z is passed through thelower set of holes or apertures, so that the base or platform can beplaced on top of a rail and the dog or jaws permitted to reach the spiketo-be extracted. The device is thus employed when working aroundswitches, especially at the convergent points of the rails thereof.

The advantages of my invention will be apparent to those skilled in theart to which it appertains, and it will be especially observed that thesame can be operated in very narrow spaces, and also that the spike inbeing extracted is pulled in a vertical line, whereby bending thereof isavoided, and also the dogs or jaws readily assume the proper positionand quickly and easily grasp the head of the spike.

I claim as my invention- 1. The herein described improved spike pulleror extractor, comprising the lever, the two depending links pivotallysecured there to and having lower slotted ends, the dogs or jawspivotally connected together and having slots in their upper ends, thenutted bolts projected through said slots and coincident holes orapertures of said links, and the main operating-lever connected to saidformer lever, substantially as set forth.

2. The herein described improved spike puller or extractor, comprisingthe base or platform, the parallel bars or posts having upper and lowerholes or apertures, the lever f ulcrurned between said bars or posts,the links pivotally connected to said lever, the dogs or jaws havinglower curved ends and slots in their upper ends, the nutted bolts passedthrough said slots and links, the main operating-lever fulcruniedbetween said bars or posts, and the strap-irons connected thereto and tosaid former lover, substantially as set forth.

In testimony whereof I affix my signature in presence of two Witnesses.

PHILIP FOWLER.
